Abstract
The invention relates to a transmission mechanism of a vertical lathe main electric motor. The transmission mechanism comprises an electric motor, wherein the electric motor transmits power to a transmission shaft thorough an electric motor coupler, then transmits the power to a rigid coupler from the transmission shaft and transmits the power to a speed changing box through the rigid coupler. The transmission mechanism is characterized in that the electric motor coupler is an elastic pin coupler, and the transmission shaft adopts double-key symmetrical connection and transmission mode. The electric motor is moved towards the right to shorten the length of the transmission shaft by one third, and the outer diameter of the transmission shaft is increased by 1-5mm. The rigid coupler adopts double-key connection. One guiding sleeve is welded on the circumference face of one end of the electric motor coupler. The transmission mechanism is low in cost, high in rigidity, strong in bearing capacity, large in transmitted power and accurate and stable in transmission.
Description
[technical field]
The present invention relates to machinery manufacturing technology field, relate to a kind of vertical lathe main motor transmission mechanism.
[background technology]
The 3.4mm queen post vertical lathe that many producers often use, the motor that its main drive gear power source of C534J is 55KW, it passes to gearbox through power transmission shaft with power by shaft coupling.Its structure as shown in Figure 1, motor reel 1 is by helical spring shaft coupling 2, power is passed to the power transmission shaft 3 of fixed mounting base, and then through positive coupling 5, pass to gearbox 6, this structural requirement motor output shaft center, center, power transmission shaft fixed mounting base hole, gearbox high speed shaft center three must be positioned on the same axial line, guarantee the torque of coaxial ability normal delivery.If the different axis of three, the rotating mechanism imbalance, because increase and the fluctuation of supporting force appear in The Effect of Inertia Force, damage bearing when serious, lower efficiency, produce noise, make basic the generation vibrate or resonate, even make helical spring shaft coupling mating surface produce pressure feedback inefficacy, spring is distorted, the keyway at fracture, power transmission shaft two ends rolls key and tears phenomenon, so that can't keep the operate as normal of this mechanism.
This lathe is if put into production use year for a long time, long-term vibration can make immerge, whole displacement (sink and tilt) takes place in two columns, consequently produces the different axis of three thereby cause center, cardan-shaft suspension seat hole to move down (because supporting base is installed on the column side).Along with the increase of this kind duration of service, it is more and more frequent that this kind phenomenon takes place, even cause just changing one less than two months and want power transmission shaft, less than the result who just changed a pair of shaft coupling in a year.And the very difficult purchase in market of this kind shaft coupling, both had a strong impact on production, increased a lot of workloads to machine maintenance again.Draw mechanism and all be installed in the melt pit, maintenance is extremely inconvenient.
[summary of the invention]
Shortcoming at prior art, technical problem to be solved by this invention, overcome the deficiency of above-mentioned prior art exactly, a kind of with low cost, rigidity is higher, bearing capacity is strong, transmitted power is big and transmission is stable vertical lathe main motor transmission mechanism is provided.
The technical solution used in the present invention is: a kind of vertical lathe main motor transmission mechanism, comprise motor, power is transferred to power transmission shaft, is transferred on the positive coupling by power transmission shaft by the motor shaft coupling, transmit power to gearbox by positive coupling, it is characterized in that: described motor shaft coupling is elastic dowel pin shaft coupling, the kind of drive that described power transmission shaft adopts two key symmetries to connect.
Further, described motor moved to right shorten 1/3rd of described propeller shaft length, increase its external diameter 1～5mm.
Further, described positive coupling is two key connecting.
Further, fairlead of welding on the end periphery of described elastic dowel pin shaft coupling.
The invention has the beneficial effects as follows: this vertical lathe main motor transmission mechanism is with low cost, rigidity is higher, bearing capacity is strong, transmitted power is big and transmission is precise and stable.
[description of drawings]
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the main motor transmission mechanism of prior art vertical lathe;
Fig. 2 is structural representation of the present invention;
Among the figure: 1 motor reel, 2 helical spring shaft couplings, 3 power transmission shafts, 4 movable axis supporting bases,
5 positive couplings, 6 gear-box axles, 7 columns, 8 gearboxes, 9 motor, 10 elastic dowel pin shaft couplings
[specific embodiment]
Referring to accompanying drawing 2, the present invention has adopted a kind of vertical lathe main motor transmission mechanism, comprise motor 1, power is transferred to power transmission shaft 3, is transferred on the positive coupling 5 by power transmission shaft 3 by the motor shaft coupling, transmit power to gearbox 8 by positive coupling 5, it is characterized in that: described motor shaft coupling is elastic dowel pin shaft coupling 10, the kind of drive that described power transmission shaft 3 adopts two key symmetries to connect.
Employing resilient key shaft coupling 10 rigidity are higher, bearing capacity is high, transmitted power is bigger, adopt two keys symmetries to connect the kinds of drive, make power transmission shaft 3 bilateral symmetry transmitting torques, improve its transmission stability.
Further, described motor 1 moved to right shorten 1/3rd of described power transmission shaft 3 length, increase its external diameter 1～5mm.
Further, described positive coupling 5 is two key connecting.
Further, fairlead of welding on the end periphery of described elastic dowel pin shaft coupling 10.
Contrast accompanying drawing 1, the movable axis supporting base 4 that will connect with column 7 removes, cut down the number of intermediate links, motor is moved to right, shorten propeller shaft length, increase its external diameter, can improve transmission person's rigidity, connect with gear-box axle 6 with two key positive couplings, at last at fairlead of motor shaft coupling one end periphery welding, two half a couplers are fixed on the same axis, guarantee the two coaxial rotation.
At this preferred embodiment that this invention has been described, comprise that the inventor is used to implement known optimal mode of the present invention.The change of preferred embodiment is apparent for those of ordinary skills after reading above-mentioned explanation.The inventor wishes the change that the those of ordinary skill rational Application is such, and the inventor thinks and offers some clarification on different application at this and also can realize the present invention.Therefore, the present invention includes all modifications and the equivalents of the purport of quoting in the claim of enclosing, this allows in the law that is suitable for.In addition, any combination of all possible change of above-mentioned key element is also comprised by the present invention, unless point out in addition or obvious contradiction in context at this.
